We had to wake up the kids, our neighbors (who don't have a basement) came over and stayed for a few hours. We all slept in the basement. Muddy water seeped in through the drain in the floor of our bathroom, but not too much.
We have a least two more nights of tornado weather to look forward to.
Toto, I think we're not in Arizona anymore.
